掺铝多孔硅光致发光谱研究

Study on Spectrum of Aduterating Aluminium of Porous Silion

报道了多孔硅掺入杂质铝处理的一种新方法。观测了处理后多孔硅的光致发光谱 ,其光谱出现 4个与铝杂质能级有关的发光带。

This article reports a new method of processing porous silion adulterated with the impurity, Aluminium.By observing the photoluminescence spectrum of porous silion after disp o sal, we find that the spectrum appears four luminescence bands relatin g to the impurity's energy level which results from the recomposition for carriers at the higher energy level.
